Abstract (en)
[origin: WO0216866A1] The invention relates to a method for measuring the surface height of a material bed transported on a conveyor belt to continuously operated thermal treatment, i.e. to continuously operated sintering, when said material bed is formed of single spherical and fragile particles. According to the invention, the material bed (3) formed on the conveyor belt (4) is illuminated, essentially in the transversal direction of the conveyor belt (4), by at least one light source (5), so that the light beam (6) forms an essentially linear light streak (7) on the surface of the material bed (3), and that for registering said light streak (7), there is used at least one camera (8) and at least one image processing arrangement (9) connected to the camera (8), and that in the image processing arrangement (9), the obtained surface height image is compared with a predetermined, desired surface height image in order to detect deviations in the surface height, and that said image processing arrangement (9) is connected to an automation unit (10) in order to correct the deviations in the surface height.
